The patch titled Subject: mm/vmscan.c: consider swap space when deciding whether to continue reclaim has been removed from the -mm tree. Its filename was mm-vmscanc-consider-swap-space-when-deciding-whether-to-continue-reclaim.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Minchan Kim <minchan@xxxxxxxxxx> Subject: mm/vmscan.c: consider swap space when deciding whether to continue reclaim It's pointless to continue reclaiming when we have no swap space and lots of anon pages in the inactive list. Without this patch, it is possible when swap is disabled to continue trying to reclaim when there are only anonymous pages in the system even though that will not make any progress.
